Abstract

PURPOSE:To evade disabled connection due to registration error by analyzing an equipment address in existence in reception information and registering the result automatically in a management table as required. CONSTITUTION:The attribute of an opposite equipment is included in the information received from a line in addition to an opposite equipment address and a data. When communication processing section 1 acquires reception information, it is given to an analysis means 2 with control information. Whether or not the equipment address acquired by the analysis means 2 is registered in a management table 10 is discriminated and when unregistered, a registration means 4 is started and then a reception data processing section 7 is started. When the registration means 4 is started, it processes to register the equipment address and attribute acquired by the analysis means 2 in the management table 10. When the reception data processing section 7 is started, the section 7 seeks the same equipment address as that included in the reception information from the management table 10 and acquires the attribute to process the reception data.

受信データ処理部７を起動する。When the reception determining means 3 is activated, it determines whether or not the device address acquired by the analyzing means 2 is registered in the management table 10, as shown in FIG. 3, for example (331).
, if not registered, activate the registration means 4 (532), and then activate the received data processing section 7 (333). Also,
If the registration has been completed, the received data processing section 7 is immediately activated without activating the registration means 4.

登録手段４は起動されると、例えば第４図に示すように
解析手段２で取得された装置アドレスと属性とを管理テ
ーブル１０に登録する処理を行なう（Ｓ４１）。When activated, the registration means 4 performs a process of registering the device address and attributes acquired by the analysis means 2 in the management table 10, as shown in FIG. 4, for example (S41).

一方、受信データ処理部７は起動されると、受信情報中

を起動する。When activated, the transmission determining means 5 determines whether or not the destination device address to which data is to be transmitted (this is given, for example, from an application program) is registered in the management table 10, as shown in FIG. 5, for example. 551
), if not registered, activate the registration means 4 552),
Thereafter, the communication processing unit 1 is activated (S53). In addition, if it has already been registered, the communication processing unit l can be used without starting the registration means 4.
Start.

登録手段４は起動されると、受信の場合と同様にデータ
を送信すべき相手装置アドレスとその属性（これも例え

。On the other hand, when the communication processing section 1 is activated, it sends out to the line 11 information in which the device address registered in the management table 10 and its attributes are added as necessary to the data to be transmitted.

前述のようにして、ある装置からの受信情報を受信する
と、その相手装置のアドレスと属性が管理テーブル１０
に登録されるので、以降のその装置との送受信は登録さ
れた装置アドレス及び属性を使用して行なうことができ
る。As described above, when reception information is received from a certain device, the address and attributes of the other device are stored in the management table 10.
Since the device is registered in , subsequent transmission and reception with that device can be performed using the registered device address and attributes.

ことができる。Further, when the communication termination section 9 detects that a series of communications with a certain device has ended or that a line failure has occurred, the release means 6 is activated from the communication termination section 9, and the release means 6 is activated.
For example, as shown in FIG. 6, the device address stored in the management table 10 is deleted. That is, the device address is released from the management table IO. As a result, the erasing area of the management table 10 can be used when communicating with another device next time, and the required capacity of the management table can be reduced.

きる。As explained above, according to the present invention, the address of the communication partner device for data communication can be automatically recognized and registered in the management table, so this can be applied to, for example, a communication method as shown in FIG. This eliminates the need to register the address of the other party's device in advance, and it is possible to avoid connection failures due to registration slips that occur when registration is done manually.

更に、装置アドレスの変更等があってもシステムを停止
